[font color=\'#000000\']Probably 16-20MP and other cool stuff.
But even if the 1Ds-MkII or whatever trumps the D2X in MP count, I'd still be very happy and content with 12.4MP, provided that it lives up to the billing.
I need not only higher resolution, but almost, if not equally important, wider DR in the highlights, less color fringing, and long exposures without alot of hot pixels. With my D1X, I can only get up to 3-4 secs at best before a bunch of annoying color dots invade and swamp my pics. Also, better battery life then I've gotten with these NIMH EN-4s. I had a guy down in SC rebuild them, and they are a lot better now, but still not as good as the LIoN batts.
Oh, and here's a biggie that would really really help speed up my workflow, an auto orientation sensor like the D2H, and I believe D70 have. I get tired of having to rotate all the verticals after the fact. Very time consuming.
If the D2X can deliver on all that, I'll be a very happy camper.[/font]
